摘要：
Embrittlement of Cr-Ni-Mo welded joints (containing up to 2% nickel and up to 0. 012% phosphorus) in slow cooling after high-temperature tempering is caused by the combined effect of nitrogen, silicon, and manganese. The resultant level of the transition temperature to the brittle condition of the weld metal is satisfactorily reflected by parameter P//T//t, which characterises the combined equilibrium concentration of nitrogen, silicon, and manganese at a specific degree of embrittlement. At higher nickel and phosphorus contents, the development of reversible temper embrittlement of welded Cr-Ni-Mo welded joints is governed by different relationships.
